It is noteworthy that the optical module itself does not have FEC function.
The silicon waveguide is an important passive structure in the silicon optical module.
You know, after long-term training, all the optical module manufacturers pursue the principle of zero-error quality.
In the solution, different DWDM wavelengths can be configured andoutput in the same optical module.
G QSFP28 SR4 optical module also has excellent eye pattern, receive sensitivity and electric eye joggle performance.
This is a fallacy of weakening the capability of optical module manufacturers.
First, the application of 25G tunable optical module from laboratory to industrial environment will take at least 2-3 years.
The oversized lens applied to the camera suggests the presence of a high-performance optical module.
Matching with the transmitting end, the optical module also needs a receiving detector that receives the optical signal.
At present, the latest standard V7.0 maximum operating speed(line bit rate) has been up to 24.3Gbps,so 25Gbps SFP28 optical module can meet its needs.
The 8x 25G NRZ reduces the complexity anddesign difficulty of the 200G optical module and avoids the development cost and material cost of the difficult DSP.
In the data center optical module market, due to the large demand within 2km, coupled with the strong requirements of low cost, high speed, high density, etc.
Due to the ideal working environment of constant temperature andhumidity in the data center, optical module packaging requirements are relatively low.
Currently, silicon optical module products mainly include short-distance data center optical modules and medium-long-distance telecom coherent optical modules. .
When polarized light or fluorescence is required, the corresponding optical module can be easily mounted while all the other components remain unchanged.
The silicon optical chiptechnology is relatively mature, but there are still many technical difficulties in the packaging process from chip to optical module.
According to the 100G CLR4 Alliance led by Intel and Arista Network,the 100G QSFP28 CLR4 optical module is very suitable for connecting the super-large data center with a span of 100m to 2km.
On the one hand, the mature industry chain of 10G optical components can be used to reduce the cost of optical components,to accelerate the commercial development of 25G tunable optical module;
By analyzing the features of QSFP-DD andcomparing it to other 400G optical module form-factors, we found that QSFP-DD has unparalleled advantages in 400G applications such as data center interconnects.
On the one hand, the mature industry chain of 10G optical components can be used to reduce the cost of optical components,to accelerate the commercial development of 25G tunable optical module;
The 200G CFP2-DCO optical transceivers are a CFP2 MSA-compliant digital coherent optical module designed for line-side trunk DWDM data center interconnect(DCI), metro carrier, and regional/long haul applications.
The common QSFP+ SR4 optical module on the market actually do not have the TX optical powerreal-time monitoring function, for that is not only restricted by launch mode of VCSEL array, but also very difficult to embed a feedback optical signal on the current QSFP+ form factor.
The Gigalight 100G CFP-DCO digital coherent optical transceiver is a hot-pluggable CFP form-factor optical module designed for high-speed optical networking applications including 100-Gigabit Ethernet and OTU4.
The wavelength-tunable optical module is with flexibility in selecting operating wavelength, which is with very large practical value in DWDM system, OADM and optical cross-connection, optical switching equipment, light source spare parts and so on.
Coherent optical communication is gradually moving from the laboratory to large-scale commercial use,and the coherent optical module based on DSP processing technology often encounters the problem of large power consumption.
